Open classes are the most annoying courses for middle school students. None of them. At this time, students are often drowsy. There are definitely few people who will listen carefully to the endless talks of the old teacher with white beard on the podium.Gan Yu's classroom is ordinary and deserted. Except for the people in his own class, no one from other classes will come to listen to the class. Therefore, the classroom is empty, and there is not even one in the first five rows. There are only a few people in the sixth row at the beginning, and most of them are sleeping.Not only did Gan Yu not have a trace of fatigue and sleepiness, but he had endless energy and was full of energy. If you want to tell me why, of course it was because his girlfriend was by his side.
